Using capacitors to supply reactive power reduces the amount of current in the line. Since line losses are a function of the current squared,I2R, reducing reactive power flow on lines significantly reduces losses. Engineers widely use the “2/3 rule” for sizing and placing capacitors to optimally reduce losses.
Capacitors provide tremendous benefits to distribution system performance. Most noticeably, capacitors reduce losses, free up capacity, and reduce voltage drop. Let’s go a little bit into details. By canceling the reactive power to motors and other loads with low power factor, capacitors decrease the line current.
Most noticeably, capacitors reduce losses, free up capacity, and reduce voltage drop. Let’s go a little bit into details. By canceling the reactive power to motors and other loads with low power factor, capacitors decrease the line current. Reduced current frees up capacity; the same circuit can serve more load.
Reduced current also significantly lowers the I 2 R line losses. Capacitors provide a voltage boost, which cancels part of the drop caused by system loads. Switched capacitors can regulate voltage on a circuit. If applied properly and controlled, capacitors can significantly improve the performance of distribution circuits.
The objective of capacitor placement in the electric network is to minimize the losses and improve voltage profile. The load and capacitor model, objective function, constraints and power loss calculations are described in this section. The loads and capacitors are modeled as impedance. The impedance model of loads and capacitors are given by Eq.
The most popular result of analytical methods is the (2/3) rule. According to this rule, in order to come up with the maximum reduction, a capacitor with (2/3) drag reactive power from the beginning of the feeder must be installed in a place where its distance is (2/3) feeder length in comparison to the beginning of the feeder.
